<span>This dog, was a skinny dog. You could see her ribs through her fur. Her fur looked short, as if you could feel her skin through it. In some places, you could see a little bit of skin. Her collar had a small ID tag, with not much information. It just said “Harper” which, must have been her name. To me, she could have been Oreo. In the middle of her chest was a white streak. On both sides, blackness surrounded it. Even though she was skinny as they came, she was cute. My cute little Oreo.
“Hi, Puppy. Don’t worry, I won’t hurt you.” I gave her head a pat, remembering the same look in my old dog, Ren’s eyes. He had the same innocent eyes. Such a sweetheart... Her big brown eyes looked at me, as if to say; I know. I love you already. But, they said something else, too. They said; I have been hurt by your kind. Should I accept you? I knew that she was a rescue dog. I advanced slowly toward her, getting one inch closer at a time. I crawled over to her bed and began rubbing her silky ears. When she put her belly toward me, I realized that she was completely bald there. A few spots had little fuzzy hair, but other than that, her peachy skin showed through. I got close to her ear and whispered; “I love you. I will never hurt you. Soon, I will get you a new collar, and a new ID tag telling others, that you are my<span> dog. Forever.”
I took this out of my 6th-grade writing. I hope it works!
Best of luck!</span></span>

REM slep have chemical and electrical activities that regulate it, during this phace the brain have abundance of the neurotransmitter acetylcholine, combined with lack of monoamine neurotransmitters histamine, serotonin and norepinephrine. Some studies theorize that this make REM sleep involved in the functions of memory, however, there is not enough information to ensure that memory depends on REM sleep.
